Title: Arrangement for applying a belt to a pulley on a shaft during rotation thereof
IPC: F16H7/22
Filed: 1945-06-13
Abstract: 593,780. Belt gearing. WRIGHT, R. R. June 13, 1945, No. 14950. [Class 80(i)] A pulley 11 is provided with a conical part 11a for mounting a belt 16 on the pulley whilst it is rotating. A belt perch 12 adjacent the conical end holds the belt when idle. The belt drives a fast pulley 15 on a countershaft 13, a loose pulley 14 adjacent the pulley 15 being aligned with the conical part 11a. To start the drive the lower loop of the belt is applied to the loose pulley 14, and the upper loop is lifted off the perch on to the conical part 11a when it will ride up the cone on to the pulley 11 drawing the lower loop on to the fast pulley 15. In some drives the loose pulley 14 may be dispensed with.

Abstract: 146,703. Mallock, H. R. A. June 13, 1919. Kinematograph apparatus.-In kinematograph cameras or projectors having continuously-moving. films and comprising a revolving ring of mirrors, each mirror is carried by a mirror holder secured to a revolving bed-plate so as to be subject to six restraints only, three of the restraints being adjustable. As shown, each mirror m is carried in a mirror-holder having a thick foot 1, being held against studs a, b, c by a spring s1. The base 1 has three projections d, e and 9 resting on the bed-plate B, the projection 9 consisting of a screw. A pin 13 closely fitting a slot 4 in the base 1, and a key 11 engaging the end of the base and turning in a hole 12 determine the angular position of the base on the bed-plate. A screw 10 engaging the pin 13 determines the position of the base in the line fixed by the pin 13 and key 11. By adjusting the screw 9, the key 11, and the screw 10, the mirror can be arranged with its reflecting surface normal to the plane of the bedplate, normal to the plane passing through the axis of rotation, and half-way between the film and the axis of rotation. A screw 7 with a spring washer 8 holds the mirror in its adjusted position.

Abstract: 529,642. Moulding presses. BERRY, D. G. May 22, 1939, No. 15231. [Class 87 (ii)] In a rotary table brick machine, clay is fed to moulds on a table 62 of a horizontal pugmill 20 having an enlarged chamber 22 from which the material is fed outwardly by cams 56 and a rocking plate 58, carried by a shaft 60, the clay being severed by wires 122 in a reciprocating frame 120. An eccentric 74 on the pug shaft 26 rocks a lever 82, 83 linked to a lever 88 fast with the shaft 60. Movement is imparted to the table by a pawl 98 driven through a pin 102 engaging a recess in the end 100 ; the pin is carried by a bar 108 for a member 92, which is pivoted to a pin 90 on the lever 88 and engages by a slot 106 a pin 94 on the lever 83, and this bar 108 also carries a member 114 carrying a roller 116 adapted to ride on a fixed cam 118 to disengage the pin. The table is held by a spring locking- bolt 166 engaging prescribed holes, the bolt being disengaged by a lever 175 actuated by a lever 180 on the shaft 60. A weighted lever 182 assists the downward movement of the plate 58. The cutter is moved by a lever 142 on a shaft 136 which is rocked alternately in either direction by cam rollers 160, 158 on the driving gear 52 of the shaft 26 which rollers respectively engage a lever 144 directly geared to the shaft 136 and an arm of a second lever 147 linked to a lever 150 on the shaft 136.

An agricultural elevator of the kind adapted to be towed behind a tractor for picking-up and elevating cut crops and including an inclined endless conveyer belt has a plurality of sets of guide-bars arranged above the belt, each set being pivoted at its lower end and adapted to rest on the crops on the belt to prevent such crops from falling back down the belt, the lowermost set being arranged to guide the crops on to the lower end of the belt. As shown, the belt 34 is carried by rollers at the upper and lower ends of a frame composed of pairs of bars 1, 3 interconnected by pairs of end struts 5, 6 and supported by the struts 5 and a pair of struts 9 from an axle 14 carrying a pair of wheels 17. The front of the frame is additionally supported by a pair of castor wheels 19 which swivel in sleeves 15 carried by the struts 5 and are vertically adjustable by levers 91 which are connected to their upper ends 91, and operable by a handle 94 having locking means comprising a withdrawable detent 95 engaging a notched quadrant 96. The forward ends of the struts 5 are bent outwardly at an angle of about 45 degrees and carry a pair of rake discs 42 which are freely rotatable and engage the crop on the ground to gather it in towards the belt 34. Crops leaving the upper end of the belt 34 are discharged through a hood 79 which is pivotable about an axis 83 from the operative position shown to a retracted position, being held in either position by an over-centre spring arrangement 85. The crops are received in a cart 100 towed by the elevator. The belt 34 is driven from one of the wheels 17 by a chain 39 passed around a chain wheel 41 on the wheel 17, a snub chain wheel 40 and a driven chain wheel associated with a chain wheel 37 which is connected by a further chain 36 with the lower roller around which the belt passes. Three sets of guide bars are provided, two of which are pivoted about a common shaft 53 while the third is pivoted on a cross-tube 69. The lowermost set of guide bars consists of three bars 54 spaced across the conveyer and each provided with a bend 62 which extends into the obtuse angle between the belt 34 and the ground to guide the crops on to the belt. The bars 54 are secured to shaft 53 and urged towards the crops by a spring 60 which is adjustably connected to a lever 57, also secured to shaft 53, by the provision of a number of holes 58 on the lever for connection of the spring. The second set comprises two bars 63 arranged between the bars 54 and freely pivoted on the shaft 53 so that they act on the crops solely by gravity. The third set comprises two bars 70 urged by springs 73 towards the crop. Each set of guide bars is prevented from approaching too closely to the belt 34 by fixed stops which determine a minimum distance of the bars from the belt. Side shields 77 are also provided for preventing the crop from falling off the belt 34 laterally.

Title: Improvements relating to semiconductor devices
IPC: H01L21/00
Filed: 1965-04-12
Abstract: The electrodes of a semi-conductor device (see Division H1) are provided by depositing a <PICT:1104804/C6-C7/1> bi-metallic film, comprising a layer of molybdenum covered with a layer of gold or aluminium, over the surface of the device and etching to shape. The device may be of silicon covered with a layer of silicon oxide, the electrodes overlying the oxide except where they extend through windows and contact the silicon.  The surface of the device is subjected to a series of cleaning steps and the metal layers are deposited using the apparatus shown in Fig. 3 in which the devices 25 are supported on a stainless steel sheet 24 heated by quartz infrared tubes 26 inside an evacuated bell jar 21.  The molybdenum source comprises a molybdenum strip 29 the width of which is constricted at its centre so that when an electric current is passed through the strip the centre part is heated to just below its melting point and begins to evaporate.  The source of the covering layer comprises a tungsten heating coil 27 arranged to evaporate a charge 28 of gold. A thin flash of aluminium may be deposited over the surface before the molybdenum and gold (or aluminium) layers.

Abstract: 529,290. Dielectric guides for displacement waves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 26, 1939, No. 15704. Convention date, May 28, 1938. [Class 40 (iii)] Relates to means for matching the impedances of a transmission line and a wave guide, comprising a coupling formed by a tapered extension of the inner line conductor extending within the guide and terminated in a tapered element of dielectric material whereby conduction currents in the line are gradually transferred into displacement currents in the guide. In the Fig. the outer conductor 3 of the coaxial line 1 is of the same diameter as the pipe 31 forming the wave guide 9, the inner conductor 5 having a tapered end 6 to which is attached a tapered extension 15 of insulating material more than one wavelength long. The value of the dielectric constant of the extension 15 may be arranged to decrease towards the tapered end where it approaches the value for the guide medium; the non-uniform dielectric constant may be effected by embedding particles in the dielectric material. When a two-wire transmission line is used, the two conductors are terminated in a similar manner to the inner conductor 5 of the coaxial line.
